To all whom it may concern.- Be it known that I, Cumulus A. Herr, a citizen of the United States, residing at Blair, in the county of of Nebraska, have invented anew and useful Windmill-Lubricator, of which the following' is a specification.

My invention relates to improvements in windmill-oilers in which a reservoir to carry a su ply of lubricant is located at the top or hea of the mill; and the objects of my improvement are, first, to force a supply of 1 semii luid or hard-oil lubricant from the reser-- voi-rto the different'stationary and traveling the machine without climbing the tower; second, to facilitate the conduction of the lubricant from the reservoir to the wearing partsby a novel construction of flexible a of Figz i. Fig. 2 is a whole side elevation of the same. Fig. 3 is a plan of the rocker" ,arm 2 with its various connected parts. Fig. 0 4 is a plan of the removable top of the reservoir and the feed mechanism, and :Eig; 5 illustrates .an adaptation of the piping to different types of windmill construction.

Similar numerals refer to similar parts 5 throughout the several views.

Numerals from 1 to 9, inclusive, refer to parts ofthe windmill, and numerals IOand upward refer to the lubricator.

The common type of windmill chosen for illustrating my invention consists of the vertical sleeve '9, to revolve around the top end of a pipe projecting; up into it from the to of the supporting-tower below. This vertical sleeve 9 has an integral horizontal tube 6,

4 5 in which turns the mainsl'iait carrying the wind-wheel at its outer or front end and the spur-pinion 3 at its inner or rear end to engageand revolve the large crank gear-wheel 4, mounted on a short shaft disposed in the The sleeve also horizontal integral tube 5.

has the integral upward and laterally-projectingarm l, to the end of which is hinged the base of the rocker-arm 2. By the pitrnan 8 the swinging end of the rocker-arm is connected at one sidewith the wrist 4 on the gear-wheel 4,

The pipes which convey the lubricant to the different parts of the mill are connected through hi's f ower head. 1 The upper head .15 of the cylinder or r voir is removable to facilitate filling thdres?

A sleeve 19 envelope the piston-rod between P the guide-bar 17 and the Wheel-nut to-prevent the nut from raising when it is turned forward to compress the charge of:lubricant in the reservoir. Y

The outer end of t e bar 13 is provided with the counter-' weight 14, which raises the the weight of the wire or cord 23 and back the pawl into osition for an impulse on the pin-toothed w eel-nut 11. The pawl inner end against 12 and the inner end of the bar 13 form a togmovement actuated by the line; is 1 attached near the joint and I gle or knee 23, which usually sus ended by the side of the pump rod through the pipe within the sleeve 9,

The hinge-pin 27, by which the base of the rocker-arm; 2 is pivoted to the arm 1, is usually set rigidly through the endof the arm 1, the eyes at the ends of the branches of the forked base of the rocker-arm turning on the end portions of the pin at each side of the arm 1, as shown in Fig. 3. For this pin I use a longitudinallybored bar or piece of pipe with the forward end plugged. I The rear end of the pin projects beyond the bearing and is provided with the o enin 26 on topofthe projecting end, by w oh the lower end of the supply-pipe 26, leading from the reservoir above, 1s connected.

This union-joint p1pe-coupling serves as a bin e o'r flexible joint in the pipe and allows tl ie end of the pipe 24 that is connected to the pin 30.to the arm 2 independ ent of the stationary hingepi n 27, to which its opposite-end is coupled.

The oil-hole 3 2 is elongated in or in the direction of the Inovementof tie journal-box on the pin, as shown. This is for the pur pose ofi ofiering a free opening at all points of movement for the flow of the lubricant into' the end of the pipe 37, which is connected to the top of the journal-box 8 and iscoupled' to the pipe 38, below which leads the lubri cant down to the box on the wrist 4 in the lower end of the'pitman. In some ty es of s exactly t' 's manner of piping the rubricant is impracticable; Then instead of the pipe 24, the single union-joint couplin i 25, I substltute the construction illustrated rod between the guide-bar and I in Fig. 5 This is a more extended lication of the same principle. Here the ubricant is conducted directly in an independent line from the reservoir to the bearings on the movable end of the rocker-arm. use three sections of rigid pipe 42, 43, and 44, besides the part 37, disposed in angular form, as shown, and connected together by three union-joint These are .ike the unicnqoint pipe-coupling 25 and have their threaded connectionsjfas- This tamed by the key-pins 40, 40, and 40'.

It is obvious that pulling and relaxing the line 23 at alternate short intervals would 10- tate' the wheel-nut 11 and move the pistonhead downward, forcing the lubricant out through all the connected pipes to the r'nachine-bearings.

By removing the head 15, which is simply bolted on, the reservoir is recharged. The pawl is raised and the pin-toothed wheel-nut revolved backward with the fingers until the piston head is drawn up to its under side, when the head may be replaced on the filled reservoir.
